PAPER-ROLL MECHANISM FOR PRINTING-PRESSES.

Original application filed. March 27, 1912, Serial No. 686,476.

Specification of Letters Patent.

24, 1916. Serial No. 73,877.

To all whom it may concern Be it known that we, JosnrI-I J. WALSER and CHARLES A. Danssnn, citizens of the United States, and residents of Chicago and Glencoe, respectively, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paperlloll Mechanism for Printing-Presses, of which the following is a specification, reference being had to the accompanying drawmgs.

This invention relates to paper roll mechanism for printing presses and it has for one of its objects the provision of new and improved means for centering the roll of paper in proper position relative to the press when it is being inserted in the press.

It is another object of our invention to provide for moving the paper roll shaft at the same time into proper operative position by the roll-centering operation.

It is another object of our invention to provide new and improved means for re moving the reel from the press after the web has been exhausted from the reel.

It is another object of our invention to provide suitable connections between the reel-removing device and the roll-centering devices whereby the weight of a fresh roll of paper being inserted in the machine may be utilized for centering the roll in the press.

It is another object of our invention to improve devices of this type in sundry details hereinafter pointed out.

The preferred means by which we have accomplished our several objects are illus trated in the drawings and are hereinafter specifically described.

That which we believe to be new and desire to cover by this application is set forth in the claims.

In the drawings :-Figure 1 is a front view of a roll of paper in position in the framework of a press, only fragmentary portions of the framework being shown, the view illustrating our improved devices; Fig. 2 is a vertical cross-section taken substantially on line 2-2 of Fig. 1, but slightly enlarged; and Fig. 3 is a horizontal section taken substantially on line 33 of Fig. 1, but with the parts in changed position.

Referring to the several figures of the drawings in which correspondlng parts are left upon the reel.

indicated by the same reference characters, 10 indicates the framework of a press provided with socket members 11 adapted to support a shaft 12 having a reel 12 provided with a roll 13 of paper or any other suitable web material fixedly mounted on the shaft in properadjusted position longitudinally of the shaft. The framework 10 comprises horizontally-extending arms 14: along which the shaft 12 is adapted to be rolled for the insertion of a fresh roll of paper fixedly mounted on the shaft. The socket members 11 are provided with diagonally-disposed slots 15 open at their upper ends, into which slots the shaft 12 is adapted to pass from the arms 14:.

16 indicates a lever provided with a hub 17 which is journaled in the framework 10. Fixed in the hub 17 is a rock-shaft l8 supported at its outer end by a sleeve 19 supported by a bracket 20 mounted on the framework 10. Fixed upon the outer end of the shaft 18 is an arm 21. An arm 22 of corresponding eflective length is mounted upon the hub 17. Each of the arms 2122 is provided at its outer end with an upwardly-opening socket 23, the sockets 23 being located in such a position that when the lever 16 is moved in clockwise direction in Fig. 2' the sockets 23 are brought into engagement with the shaft 12, serving to lift the shaft 12 evenly out of the diagonally- 85 disposed sockets 15 into position upon the arms 14: whence the shaft 12 and the reel 12 are adapted to be readily removed from the press, together with whatever paper is 2425 indicate brackets mounted upon the framework 10 at th'e opposite ends of the roll 13 having rack-bars '2627 slidably mounted therein, said rack-bars 26-27 being provided respectively with plates 2829. The rack-bar 26 meshes with a pinion 30 fixedly mounted upon a shaft 31 suitably supported from the framework 10 and adapted to be rotated by the shaft 18 through the medium of intermeshing bevel gears 32-33. The rack-bar 27 meshes with a pinion 3st fixed upon a shaft 35 suitably supported from the framework 10, the shaft 35 being rotated by the rock-shaft 18 through the medium of intermeshing bevel 105 gears 3637.

When the lever 16 is given a stroke in clockwise direction in Fig. 2, the shafts 3135 are rotated in opposite directions for moving the plates 2829 outward away from the ends of the roll 13. At the end of this stroke the shaft 12 is lifted out of the sockets 15 as above described into position upon the arms 14. The shaft 12 and the reel 12* are then removed from the machine and another shaft 12 having fixedly mounted thereon in adjusted position another reel 12 bearing a fresh roll 13 is placed in position upon the arms 14, the lever 16 being held in its lowered position during this change. When the shaft 12 is rolled into the sockets 15, it comes into contact with the sockets 23 of the arms 21-22 I whereby the weight of the roll and its connected parts serves to give the lever 16 an upward impulse serving to bring one of the plates 2829 into contact with one end of the roll 13. When the lever 16 is moved to the limit of its motion in counterclockwise direction in Fig. 2 the plates 2829 are both brought into firm engagement with the ends of the roll 13, serving thus to center the roll in the desired position. Inasmuch as the roll 13 has previously been fixed in the predetermined desired position upon the shaft 12, the shaft 12 also is moved by this operation into the desired adjusted position longitudinally of itself. After the operation of centering the roll and the shaft has been completed, the lever 16 is to be moved back into approximately the position shown in Fig. 2, in which position the plates 2829 are held slightly out of contact with the roll 13 as shown in Fig. 1.

In the structure illustrated in our application, Serial No. 686,476, filed Mar. 27, 1912, of which the present application is a division, means is shown in connection with the shaft 12 for controlling the rotation of or braking the roll 13, but it is not believed to be necessary to illustrate such controlling means in this application, as it is not claimed herein.

What we claim as our invention and desire to secure by Letters Patent, is-
